by replacing it with a multiplication. Said multiplication can't
overflow an int32_t because lpc_coefs is limited to 16 bit precision.
Fixes the FACE-test acodec-ra144 as well as part of #8217.

I am unable to reproduce the division by zero mentioned in ticket #8217;
probably just an error on the reporter's part.
